REQUEST FOR ADDITIONAL INFORMATION l
IE BULLETIN 85-03 i'
1.
~ Has water hammer due to valve closure been considered in the deter-mination of pressure differentials?
If not, explain.
2.
MOV HV-2452 is shown normally closed in the steam line from the steam generators to the auxiliary feedwater turbine, in Zone C-5 of Drawing 2323-MI-0202 Revision CP-7 (Unit 1).
This M0V is not listed in Table 1 of TU Electrics's May 14, 1986 response; however, i
it is included as HV-312 on Page 28 of the Westinghouse Owner's Group l
Report of March 1986.
Revise Table 1 to include this M0V, or justify l
its exclusion. As required by action item a of the Bulletin, assume inadvertent equipment operations.
3.
The proposed program for action items b, c and d of the Bulletin is incomplete.
Provide the following details as a minimum:
(a) commitment to a training progran for setting switches, maintaining valve operators, using signature testing equipment and interpreting signatures; (b) description of a method possibly needed to extrapolate valve stem thrust measured at less than maxinum dif-ferential pressure; (c) justification of a possible alternative to testing at maximum differential pressure at the plant; and (d) stroke testing when necessary to meet Bulletin requirements.
